INVENTOR STATES PATEN OFFICE WILLIAM DOUGLAS KILIBQURN, .OF Mommy,UTA-H.

Be it known that I, WILLIAM DOUGLAS KILBoURN, a citizen of the UnitedStates, and a resident ofMurray, in the county'of Salt Lake and State ofUtah, have invented a new and Improved Method of'Handling Matte, ofwhich the following is a full, clear, and exact description.

Among the present invention has in view are: To provide a method ofhandlingmatter to fracture the same into particles which may be manuallyhandled; to provide a method of handling matte buttons whereby the sameare fractured into particles readily reduced for treatment; and toprovide a method of handling the matte buttons which is simple andreadily performed.

One embodiment of the present invention is disclosed by the structureillustrated in the accompanying drawings, in which like characters ofreference denote corresponding parts in all the views, and'in whichFigure l is a vertical section of a matte pan containing the mattebutton partially cooled, the anchor key being held therein; Fig. 2 is a.top plan view provided for assisting in and controlling the fracture ofthe matte button; and Fig. 3 is an illustrative View in vertical sectionshowing the bleeding pan in position to bleed the matte button.

The drawings above set forth are provided to aid in'the description ofthe-method herein set forth. Other means might be employed with acertain measure of success. At present the matte from the smeltingfurnaces. for reducing metalbearing ores is drawn from the crucible intowide flat circular pans orbowls, designated in t e present drawings bythe numeral 4. The pans 4 are placed to receive the matte from thefurnaces, having had previously deposited in a the center thereof aloose anchor pin 5, about which it is the design of the operator thatthe matte should freeze. The pin 5 is provided with an eyelet 6, towhich the grab hook of a suitable derrick is attached when it'is desiredto lift the matte button from the pan for removal to be subjected tofurther treatment incident to this method.

In the following methodthe pans 4 are washed withthin liquid clay, whichcauses the separation betweenthe button and the pan when the button. israised from the said pan. In the present :method the button 7Specification ofiLetters Patent. Application filed February 25, 1910.Serial No.'545,821.

is so raised when, after from one'to three hours, there is formed asolidified wall 8 in direct contact with the pan 4 and a wall 9gormcilng the upper'crust. Between the walls an istransferred b pan 4deposited the bleeding pan, for the reason that it is by resting in thepan that the buttonis'bled of the molten mass 10. The pan 11 is providedwith trunnions l2, 12. In the operative position of the pan 11 thetrunnions 12, 12 are mounted in suitable bearings in standards providedtherefor. The pan'll is also provided with a out which is illustrated inFig. 2 as being V- shaped, and is disposed-at a point-equidistant fromthe trunnions 12, 12. When the button 7.is transferred from the pan 4 tothe pan 11, the pan 11 is tilted to overbalance the side of the pancarryin the cut away portion 13. At the moment 0 the button 7 in the pan11 the side of the pan having the cut away portion 13 is properlysupported by suitable props. It is while the pan is in a substantiallyhorizonal position that the edge of the button 7, overhanging the cutaway portion 13, is broken away by striking the samewith a sledge orother suitable device. The fracture 1n the button 7 thus producedcarries away sufficient of the edge of the button 7 to expose the molteninass at the interior of the same and between the walls 8 and 9. Thefracture having been thus made, the props supporting the pan 11 'areremoved, permitting the pan to tilt to the position shown in Fig. 3above a third pan 14. The pan 14 is of a dimension suitable to receive asmall and thin button 15 formed by the material from the interior of thefirst and larger button. When the mass 10 has been entirely bled fromthe first but-ton, the hollow shell is then lifted out of the pan 11and" placed on a breaking platform or car where it is subjected tocooling. by means of water thrown thereon by hosing. The smaller aroundanchors 16, provided with eyelets 16 and set up in the pan 14 rior topouring the molten mass 10. These uttons, as soon as solidified, aremoved to the breaking platform or car and treated in the manner similarto that described with reference to the shells from the center of whichthe said buttons have been formed. When the water strikes the highly Y asuitable derrick from the in a pan ll, termed by me away portion- 13,

placing i heated mass, a rapid and unequal contraction results,particularly in the shells formed by the walls 8 and 9. This results infracturing the shells into small and readily handled masses. I havefound, in use, that after properly hosing both the shells of the largerbuttons and the solid mass of the smaller buttons, that the particleshave been so finely comminuted as not to require manual handling orbreaking by hammer.

Having thus described my invention, what I claim as-new and desire tosecure by Letters Patent is p 1. The method of handling matte,consisting in pouring molten matte into a cooling pan to form acontaining shell; thenbleeding the interior of said shell of the moltenmass therein; and then cooling the said shell at a rate to fracture thesame.

2. The method of handling matte, consisting in pouring molten matte intocooling receptacles to orm a continuous solid shell having a moltencenter; then bleeding the said shell of the said molten center bydrawing'the' said molten center into shallow receptacles to form a thincake; and then rapidly cooling the said shell-and said cake to fracturethe same.

3. The method of handling matte, consisting in pouring molten matte intoshallow cooling receptacles to form a thin edged button; then removing asection of the edge of said button to form an opening to expose themolten mass contained within the center thereof; then decanting the saidmolten mass through the said opening; and then rapidly cooling the shellto cause automatic fracture thereof.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
